@eleanxr_dunkin This is not likely to be an issue with your discs overall. There could be an issue with your Generations disc, but if your game was working before, it should still work now. While there's only limited official support for people with used discs, the discs themselves can work, and an install that involves used discs is no more likely to fail than one that involves discs still in the possession of their original owner.
Did you run the Super Patch? It's specifically made for disc installs and doesn't have anything to do with Origin. If it doesn't or didn't help, try running a couple of basic checks on your Windows system files. Here's how:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Command prompt (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
- Post the message you receive here
